The FDA said it developed the document to assist drug sponsors who are planning to use minimal residual disease (MRD) as a biomarker in clinical trials conducted under an investigational new drug application or to support FDA approval of products intended to treat hematologic malignancies.

“As a result of important workshops where we’ve heard from stakeholders and an analysis of marketing applications showing inconsistent quality of MRD data, the FDA identified a need to provide sponsors with guidance on the use of MRD as a biomarker in regulatory submissions,” FDA Commissioner Scott Gottlieb, MD, said in a statement.

The guidance explains how MRD might be used in clinical trials, highlights considerations for MRD assessment that are specific to certain hematologic malignancies, and lists requirements for regulatory submissions that utilize MRD.

MRD could potentially be used as a biomarker in clinical trials – specifically as a diagnostic, prognostic, predictive, efficacy-response, or monitoring biomarker, according to the draft guidance. Additionally, MRD could be used as a surrogate endpoint or “to select patients at high risk or to enrich the trial population.”

The draft guidance also provides specific considerations for MRD assessment in individual hematologic malignancies, including acute lymphoblastic leukemia, acute myeloid leukemia, acute promyelocytic leukemia, chronic lymphocytic leukemia, chronic myeloid leukemia, and multiple myeloma.

The full document is available on the FDA website.
